Hi @mmcky,

Just a quick heads-up — I'll be merging this and making it live once it builds!

[mmcky]

Pull Request Overview

This PR restructures the likelihood ratio processes lecture into three focused lectures with additional content: one on divergence measures, another on Lawrence Blume and David Easley's heterogeneous belief model, and a third on VAR likelihood ratios. The changes enhance theoretical coverage and provide new examples while maintaining consistency across the quantitative economics curriculum.

• Breaks down the comprehensive likelihood ratio lecture into specialized topics
• Adds three new lectures covering divergence measures, heterogeneous belief models, and VAR applications
• Enhances existing Wald-Friedman content with improved code structure and exercises

@HumphreyYang if you don't have time to review the copilot results -- not to worry (just resolve them if you wish). Some are useful, others we can ignore.
